Main way.
Common synthetic fibers complex method has following two: the first be carried out on mass of fibers it is compound, i.e., by two
Kind or two or more polymer pass through a spinneret orifice spinning.There are two on same section for the fiber processed by this mode
Kind or two or more immiscible polymer, but this fiber is still monofilament.
Second of composite fibre is that compound, i.e., common combined yarn is carried out by two bundle fibers, the products such as cladding wire (yarn), it
The one kind for also belonging to fibre in differentiation is the multifilament as made of geometric shape or physical property different combination of monofilaments, generally adopts
With false twisting and twist, the modes such as air-flow interlacing carry out it is compound.The composite fibre as made from this method can be mentioned largely
The natural sense of high synthetic fibers, to achieve the purpose that imitated natural fabric.
Currently, cladding wire relies primarily on two kinds of processing method productions: one is Mechanical entanglement claddings, referred to as " machine packet "；Separately
One is air network claddings, referred to as " sky packet ".Domestic existing low lead relies primarily on " machine packet " than spandex+polyamide fibre air-coating silk
Mode produces, low efficiency, at high cost.
